MOLLUSCA OF INDIA. 435 



Concluding Eemaeks. 



With the completion of this part, the last of Volume II., I trust 

 to supply early in 1915 an Index of Genera and Species. At the 

 same time, as a supplemental part or volume, I hope to complete 

 what I have put together concerning the geographical distribution 

 of the genus Alycmus and of many other Indian genera I have 

 treated of in the two volumes, particularly in connection with 

 the physical features of the country past and present. Also to 

 publish tlie results of Avork completed on the animals in the 

 genera Anadenus, Sivella, Planispira, Plecfotropis, jEgista, Qanuena, 

 Glesnda, Succlnea, &c., including many new species.
